This is one of the simplest and also coolest DIY key holders we've seen so far. All you need are a couple of Lego pieces to create your own customizable Lego key holder.

Kate on Minieco found that Lego part number 3176 makes an excellent keychain piece that you can snap onto another block stuck onto the wall with strong double-sided foam tape.

With or without the stormtrooper piece, this clever project is almost as geeky as making an ethernet plug key holder but probably more fun. The creative possibilities are almost endless, with different sizes, colors, and other pieces you can use for your key holder.
